Hermie or Foxtailing???

No reason at this point to chop early. It's not unusual for plants to throw out some nanners late in flower - it's called rodelization.

 

It depends on when the nanners appeared. If it's just within the last couple of weeks, that's not long enough for a seed to mature. There's nothing wrong with a few seeds.

 

Very normal for a plant to through a few at the end of its life. It's a last ditch attempt to pass on its genetics. I often allow my plants to flower longer than needed in order to obtain seeds. Rodelization is a great but not often used way to save genetics.

As a buyer seeds are weight which means less bud.

As a grower seeds arent always a bad thing.

 

They do release pollen so theres a chance. This late in flower I wouldnt worry about it if the other plants are roughly just as far along. It wont be many seeds and unless you let the plant flower longer than needed it will just be a few immature seeds at best. When I practice rodelization, I allow my plant to go to the point that the majority of the trics are amber. I'm trying to obtain seed though. Harvest when you're plants ready and you probably will have very few if any mature seed

 

Those the calyx swelling happens as it ripen

 

Uh oh you have dicks coming out of your bud! Just kidding I think I do see a couple nanners. However the flowers look great. Little foxtailing but not bad.
